I don’t know, I’ve got both and the 4k remastered blu-ray in motion looks much more filmlike to my eyes than the WOWOW release.
Well, that’s personal preference of course, as I feel the WOWOW looks more film like, since it has more negative grain, and I feel the bluray has that plastic look consistent with heavy DNR.
Sure, there might be some places where the 4k remastered blu-ray is softer than the WOWOW release but I’m sure there are places where the WOWOW release is softer than the 4k remastered blu-ray. In terms of how the two transfers feel when you’re watching them in motion, its night and day, the 4k remastered blu-ray feels like film while the WOWOW feels digital.
Having compared a large number of frames for both releases, I haven’t come across a shot where the WOWOW is softer, yet. Here’s another example, where I matched both the WOWOW and the bluray to the DVD.

However, like you said, it’s a matter of preference.
